Abstract :
The running of the QCD coupling constant as well as multiplicative cascades of varying depth are found to give rise to data collapsing behavior of the multiplicity distributions after suitable location and scale change in the logarithm of multiplicity. Hence the onset of a log-KNO scaling law is predicted in high-energy collision processes. It is shown that the available multiplicity data in e+e− and pp̄ collisions can be collapsed onto the same scaling curve.
